Victorian Greens MP Greg Barber told Insiders this morning that local voters will not be distracted by the federal mudslinging.

"We're getting a lot of feedback from the voters that in Victoria it's the opposite of the federal death struggle," he said.

"Down here it's just a political vacuum. Neither of the big parties are talking about the big issues.

"If you're on a crowded train every day, your train's been cancelled, if some huge development's going up outside your window and you have no say in it, then that starts to drive your politics pretty strongly."

But Victoria's Labor leader Daniel Andrews says voters in the by-election should take note of the Greens performance on a federal level.

Mr Andrews says voters should judge the Greens on its federal performance, particularly the party's refusal to compromise on asylum seeker legislation.

"That was a very instructive period in the federal parliament and I think it gives great reasons why people should be voting Labor and not Green," he said.
